SAN JOSE, Calif., March 18, 2019 /PRNewswire/ -- Designers of
portable Li-ion battery-powered electronics now have a simplified
and more flexible way to add a USB Type-C (USB-C) charging system
to their products with the MAX77860 3A switch-mode charger
from Maxim Integrated Products, Inc. (NASDAQ: MXIM). This USB-C
buck charger provides the industry's first integrated USB-C port
controller and charger to eliminate the need for a separate host
controller, simplify software development and reduce overall
bill-of-materials (BOM) costs for applications such as financial
point-of-sale terminals, power banks, industrial computers,
scanners, radios, medical devices, charging cradles, portable
speakers and game players.

A wide range of consumer electronic devices are migrating to
USB-C interfaces to support rapidly advancing communication and
battery-charging capabilities, as well as smaller design size. In
current designs, the host microprocessor is needed to detect the
current level and configure the charger's input current limit.
While PCs, laptops and cell phones have driven early adoption,
USB-C adoption rates are expected to grow at 8.5 percent a year
through 2020 thanks to usage in other classes of portable devices,
according to IDTechEx.
To reduce design size as well as simplify the system hardware
and software design, the MAX77860 integrates USB-C configuration
channel (CC) port detection and a battery charger for 15W
applications. These integrated functions allow battery
charging at the fastest rate possible under the USB-C specification
and contribute to 30 percent smaller design size while also
simplifying software development. The CC pin detection feature also
shortens the design effort by eliminating the need to support
end-to-end USB port connection and allowing charging to start
automatically.
Key Advantages
- Highly Integrated: Eliminates a separate port controller
and many discrete components. Reduces the size of an inductor and a
capacitor due to a high switching frequency of 2MHz/4MHz, resulting
in a solution size that is 30 percent smaller than the closest
competitive device. This high level of integration also reduces
overall BOM costs.
- High Efficiency: High-efficiency buck reduces heat
dissipation with more than 93 percent efficiency and up to 3A
charging capability.
- Design Flexibility: Backward compatibility allows
designs to work with both USB-C and legacy BC1.2 or proprietary
adapters. Integrated analog-to-digital converter (ADC) frees up
resources in the microcontroller, while providing accurate voltage
and current measurements.
Commentary
- "The new MAX77860 from Maxim provides real advantages to design
engineers working in the growing internet of things market," said
Kimberly Majkowski, global product
manager, Power Management ICs at Premier Farnell. "It reduces cost
and design time while delivering super-fast battery-charging
capabilities demanded by today's consumers."
- "The MAX77860 dramatically reduces system complexity by
integrating the charger, the power path, the low-dropout regulator,
the ADC and the USB-C CC detection in a small 3.9mm x 4.0mm
package," said Perry Tsao, executive
director, Mobile Solutions Business Unit at Maxim Integrated. "This
level of integration simplifies the design, enabling the delivery
of more power and more functionality in minimal printed circuit
board space."
Availability and Pricing
- The MAX77860 is available at Maxim's website for $3.03 (1000-up, FOB USA); also available with select authorized
distributors
- The MAX77860EVKIT# evaluation kit is available for
$70
